1 SKIROC status LAL – EUDET France – 05/04/2007

2 Common DAQ Slice FE FPGA PHY VFE ASIC Dat a Clock+Config+Control VFE ASIC VFE ASIC VFE ASIC Conf/ Clock - Timing is the same for all detectors - Number of channels involves embedded electronic for all detectors -Outputting of data is done the same way for all detectors  Back-end of very-front-end shall be common for all detectors VFE AsicFE electronicDetector FE of VFE BE of VFE Concentrator

3 Time considerations time Time between two trains: 200ms (5 Hz) Time between two bunch crossing: 337 ns Train length 2820 bunch X (950 us) Acquisition 1ms (.5%) A/D conv..5ms (.25%) DAQ.5ms (.25%) 1% duty cycle IDLE MODE 99% duty cycle 199ms (99%) analog detectors only

6 SKIROC presentation - ECAL read out - Silicon PIN detector - 36 channels -Compatible new DAQ

7 Main features  Designed for 5*5 mm² pads  36 channels (instead of 72 to reduce cost of prototype)  Detector AC/DC coupled  Auto-trigger MIP/noise ratio on trigger channel : 16  2 gains / 12 bit ADC  2000 MIP MIP/noise ratio : 11  Power pulsing Programmable stage by stage  Calibration injection capacitance  Embedded bandgap for references  Embedded DAC for trig threshold  Compatible with physic proto DAQ Serial analogue output External “force trigger”  Probe bus for debug  24 bits Bunch Crossing ID  SRAM with data formatting  Output & control with daisy-chain Digital on FPGA for debug

11 Planning ANR

12 Planning Eudet Le module EUDET doit être terminé pour mi 2009 Nous nous accordons 6 mois de contingency L’électronique doit partir en prod en mars 2008 (+6 mois max) SKIROC sera testé à l’ordre 1 en septembre 2007  SKIROC 2 proto soumis fin 2007  Production mi 2008 ( 3 mois de retard) Gestion des risques à étudier, ce planning semble le meilleur compromis risque-retard mais il est très optimiste.

13 Différence EUDET-Module 0 Calibration hors chip Quelques composants à prévoir dehors (bord de slab) Signaux analogiques sur le slab (calibration pulse) Plus de signaux sdur le PCB (pas de sous adressage, plusieurs Clk) Gamme dynamique réduite à 2000 MIP Auto trigger par chip dans eudet, par voie dans module 0 ?

14 STATUS  Chips are due very soon MPW delayed by a couple of weeks  Test board is in fab 3 PCBs are due for next week 1 PCB in hand Assembling in house of the first PCB :now Firmware is in developpment Labview software is in development  First results for the next CALICE meeting Analogue measurements  Some more at LCWS
